Separate the proposed two-second active/scoped-drain grace from the existing sixty-second cleanup watchdog and seventy-second replacement-readiness budget. Keep API and dashboard timing aligned, cover lifecycle timing and ownership with synthetic clocks, and document interrupted-execution uncertainty. Proposal for owner review of the shared lifecycle default; does not authorize automatic replay or guarantee a two-second recovery. Refs lidge-jun#6643

@Ingwannu Could you confirm whether you accept the proposed 2-second active-turn/scoped-drain grace as the shared default for #6643, measured from restart acceptance? It can cut a still-active turn after it was sent upstream, leaving its execution outcome unknown. The proposal preserves no automatic replay; replacement readiness is not evidence that resending is safe. The 60-second cleanup watchdog and 70-second replacement-readiness budget remain separate, so this is not a two-second downtime guarantee. The draft now has a passing root typecheck, documentation production build, GUI build, 213 explicit restart/ownership/resend/layout regressions, and actual-component browser screenshots with confirmation/cancellation checks. The broader import-derived run timed out with failures, which remain under triage. I will retain draft status while the policy decision and required validation remain unresolved. AI assistance was used for this takeover and validation. |

Not landing as proposed: an unconditional 2 s drain grace can interrupt every turn longer than two seconds during a restart, and the PR also changes gui/. #6686 already made the drain answer retryable. A future change would be an explicit opt-in grace on the restart API with the 60 s default preserved. |

Scoped follow-up to the request in comment6038063475, at current head cc7cae7. I am not accepting a two-second shared default. The revised source/description now preserves 60 seconds for omission/default callers and confines shorter grace to an explicit authenticated API option, which matches the owner's direction in comment6040044757; the current diff contains no gui/ changes. The first accepted grace and acceptance-relative deadline are now represented separately from the cleanup/readiness budgets. This is acknowledgement of the revised policy shape, not approval of the whole lifecycle/management change, its authorization boundary, or a two-second downtime guarantee. Interrupted upstream work remains unknown and must not be automatically replayed. The 444 regressions and builds are author evidence; I have not independently rerun them. Current-head Cross-platform CI37646464865 and React Doctor37646464967 are action_required, not completed runtime validation. Keep those execution gates and the independent management/lifecycle review separate; no waiver, workflow authorization, service restart or branch edit was performed. |

Closing this proposal. An unconditional 2 s drain grace would interrupt any turn that runs past two seconds while a restart is in progress, and the change also edits gui/. #6686 already made the drain response retryable (503 with Retry-After and the server_restarting code), which addresses the capacity misreport. If a shorter grace is still wanted, the safer shape is an explicit opt-in grace on the restart API with the 60 s default kept; a focused PR for that would be welcome. Thank you for the detailed analysis. |

Reopening, and apologies: I closed this based on an earlier review of the unconditional 2 s default and did not re-read the current head before closing. The current head (cc7cae7) is the opt-in shape we suggested: |

Thank you, @hulkbig — this landed on Since the branch doesn't allow maintainer edits, the one review fix went into the carry. A grace below 200 ms now cancels active turns at acceptance + grace through a separate early-cut timer. The 200 ms response-flush delay before cleanup, listener stop and exit is unchanged, so the 202 still flushes, and a pending veto cancels the timer. The 60 s default, auth scope, validation and docs are yours as written. Regressions for 1 ms and 199 ms cover this. Closing in favor of #6724. |

Summary
Related to #6643. Add an explicit short-grace option to the authenticated restart API while retaining the existing 60-second default.
POST /api/system/restartcan accept a JSON body such as{"drainGraceMs":2000}. Omission and{}retain 60 seconds. The option must be an integer from 1 to 60000; malformed JSON and invalid values are rejected before starting a drain. A target-bound local restart capability does not authorize the new unsigned body option; explicit grace requires a management session or admin token.Measure grace from acceptance, including the response-flush delay, and retain the first accepted grace across repeated requests. Cleanup retains its 60-second watchdog and replacement readiness its separate 70-second budget. A short grace can interrupt work already sent upstream; it does not establish that resending is safe, and no automatic replay is added.
The dashboard, CLI, tray, joins and automatic callers retain their default. There is no
gui/or tray diff against currentdev. All seven localized API pages now match the English API contract. Documentation covers the API option, validation, idempotence and uncertain outcomes.Verification

A full local run remains impractical alongside the four-version ADK test matrix on this machine. The earlier wider run on head

A 45-file bounded recheck then recorded 1,524 pass, 1 skip and 23 failures; every remaining failure was also reproduced on that head's unmodified parent, with identical failing test names. This is earlier-head baseline evidence, not a wider-suite pass for this revision. The current 25-file regression set covers the revised API, lifecycle and authentication behavior.

This PR stays in draft until every box below is ticked. Tick all four boxes once the requirements are met:
Required local validation passed; commands, results, and any full-suite exception are documented.
I pushed my PR to a recent dev commit (at most 10 behind; a maintainer may still ask for the exact tip before merge).
I resolved all correct Codex and CodeRabbit findings.
My PR is ready for review.
